[Bug 530432] Re: suspend with sd card inserted fails to suspend, hangs, and loses USB

[Eric Miao]

Confirmed.

I've yet traced the hang to be in del_gendisk(), and confirmed it's the
same issue as fully described in the thread below:

https://patchwork.kernel.org/patch/77228/

It's not yet upstreamed which I suspect it needs a cleaner fix. So we
actually have three options:

1) enable CONFIG_MMC_UNSAFE_RESUME and to make hang only happens when
card removal is found at resume

2) or I'll try the referenced patch to see if it solves this issue

3) or we can wait for a clean fix in upstream
